Abstract: A device includes: a first portion configured to be grasped by the hand of the user, and a second portion defining a reservoir containing a control material, wherein the control material contains a target analyte in a known or predetermined concentration. A method of verifying the accuracy of an analyte monitoring device includes receiving a fluid sample, identifying the fluid sample as a control solution, and analyzing the fluid sample.

Abstract: A route viewing system includes a computing system that receives information associated with one or more routes through a network, and identifies the routes that are associated with at least one illicit user computer used by an illicit user. The computing system then obtains a source location of a source address of the routes and a destination location of a destination address of the routes, and displays the routes on a geographical display at the source location of the source address and the destination location of the destination address of each of the routes.

Abstract: An apparatus for electrochemically machining a workpiece having first and second platforms and an airfoil extending transversely therebetween includes a first cathode trio having a center cathode disposed between first and second cathodes. The center cathode is configured for electrochemically machining a first side of the airfoil, and the first and second cathodes are configured for electrochemically machining at least the first and second platforms adjacent to the airfoil first side. The first and second cathodes are movable relative to the center cathode so that they move away from each other and toward the opposing platforms during machining. A second cathode trio is provided for electrochemically machining the airfoil second side.

Abstract: A machine for electrochemically machining (ECM) a workpiece having a stacking axis and first and second opposite sides includes a pair of cathode tools. The first and second tools have first and second longitudinal axes, respectively, disposed substantially perpendicularly to the workpiece stacking axis. The first and second tools also include the first and second transverse axes, respectively, disposed perpendicularly to the first and second longitudinal axes, respectively, and substantially parallel to the workpiece stacking axis. The machine is effective for practicing an improved method of moving the first and second tools along the first and second longitudinal axes and along the first and second transverse axes, respectively, toward the workpiece for the electrochemical machining thereof. By moving the respective cathode tools along both longitudinal and transverse axes, a selectively variable resultant feedrate direction is obtained which is inclined relative to the workpiece stacking axis.

Abstract: In accordance with a preferred, exemplary embodiment of the invention, a method of forming a blisk from a workpiece is disclosed. The workpiece includes a blank having oppositely facing first and second faces defined by a radially inner housing, a radially outer top, a first edge, and a second edge. The method comprises the steps of:positioning first and second electrodes adjacent to the first and second faces, respectively, of the blank;supplying a positive voltage to the blank and a negative voltage to the first and second electrodes;channeling an electrolyte between the blank and the first and second electrodes for electrochemically machining the blank;moving the first and second electrodes toward the first and second faces of the blank; andmoving the workpiece toward the first and second electrodes.In accordance with another embodiment of the invention, an apparatus is disclosed for practicing the method.

Abstract: In accordance with a preferred, exemplary embodiment of the invention, an apparatus for forming a blisk from a workpiece is disclosed. The workpiece includes a blank having oppositely facing first and second faces defined by a radially inner base, a radially outer top, a first edge, and a second edge.The apparatus includes first and second complementary electrodes positionable about the workpiece blank. Each electrode has a support portion and a working portion. Means for channeling electrolyte from an inlet to an outlet defined between the electrodes, and means for sealing the working portions to prevent leakage are disclosed.Electrolyte is channeled between the first and second edges to finally electrochemically machine an airfoil in a single operation from the blank.

Abstract: A tool changing system for turning machines is disclosed wherein a tool magazine having a plurality of common-based tools carries the tools on a serpentine chain matrix. The tool holders are secured to the links of the chain. The tool storage magazine is removable from the tool changer base, and replaceable with a similar tool storage magazine. A tool interchange arm is carried on a dual slide assembly, wherein a first slide moves a pair of gripper fingers to positions between the tool holder block on the tool turret of the machine and the tool storage magazine. When changing ID tools, which are mounted to the face of a tool turret, a secondary slide is moved relative to the first slide, to provide additional onward stroke positioning, and a turn-around cylinder rotates the interchange arm housing and gripper fingers to bring the tools around to the face of the tool turret.
